Audi digitally modelled the Quattro Fleet Shuttle to be driven by actor Harrison Ford’s character in the film.
He was actually filmed inside an Audi A7 Sportback and the futuristic design was then added by CGI artists in post-production.

Reference: “We have created a car for a world in about 75 years, which integrated itself perfectly into the high-tech atmosphere of the movie,” said Audi design team member Björn Wehrli.

Reference: “Designing the Audi fleet shuttle quattro was similar to customising a tailor-made suit,” said chief designer for the film project Frank Rimili. “We adapted it to the requirements of the world in Ender’s Game and at the same time had to take care to preserve our brand values.”
